“7”是使用 FontVibe AI 创作的液态玻璃文字效果。圆润的流动液态玻璃字母，透明水蓝色，带湿润光泽高光和柔和内部折射，背景是浅薰衣草到蓝的渐变。

Liquid Glass lettering: molten glass mid-flow physics expressed in glossy wet, semi-transparent, organically three-dimensional volumetric glyphs. Clear-to-blue-teal color gradient: shallow edge regions carry a faint blue-green tint, while thick central volumes hold deep cyan refractive color. Internal caustic light patterns scatter through the glass body. Soft overhead diffused key lighting creates intense white specular crowns at maximum curvature points while preserving transparency. Apple Vision Pro material aesthetic, translucent and precision-finished. Letters appear poured into molds and captured mid-solidification, with fluid edge contours, extreme specular highlights, blue-cyan translucency, and no warm amber tones. Solid volumetric glass forms only: no drips, liquid trails, elongated hanging drops, or actively flowing liquid effects unless explicitly required by font-level instructions. Avoid static rigid shapes and matte surfaces. The single rendered character “7” dominates the canvas as a thick, organically rounded volumetric glyph formed from molten liquid glass caught at mid-solidification. Its glossy wet surface has subtly fluid contour transitions and softly swollen stroke volume, never rigid or matte. Semi-transparent clear glass shifts from faint icy blue-green along thin shallow edges to saturated cyan and blue-teal refractive depth through the thick upper bar and diagonal stroke. Dense internal caustic filaments, tiny refracted light fractures, and suspended pale-cyan highlights are visible inside the transparent body. Intense crisp white specular crowns trace every maximum curvature point, with a soft overhead diffused key treatment creating bright glass reflections and a narrow electric-cyan luminous edge halo. The numeral is cleanly isolated, with no drips, trails, detached particles, or external ornaments. Background is a perfectly flat pure BLACK #000000 void with nothing else.
